Jointing Solution for Puriton Barrier Pipe

Available in diameters 63 to 180mm, our Redman fittings offer a robust, leak-free jointing solution. The joint is made by simply pressurising the outer shell of the fitting using a dedicated hydraulic pump and once made, the Redman fitting provides a ‘fit and forget’, end-load-bearing and corrosion resistant joining solution.
